TECHNICAL FIELD

The present invention relates to a camera lens module, and more particularly, to a camera lens module which is configured to include five sheets of lenses, thereby implementing high resolution in a compact size.

BACKGROUND ART

Mobile terminals are gradually developed together with the increase in their amount used, and various functions and services are developed accordingly. A portable terminal such as a mobile terminal or smart phone has a camera to take photographs or moving pictures, and provides a service for storing the taken image or performing video communication. Recently, a camera module has been mounted in most portable terminals. That is, demands on micro-miniature camera modules are rapidly increased.

In a micro-miniature camera module, high resolution is implemented as the number of sheets of lenses increases. A recent camera module has a built-in auto focusing (AF) function of moving a portion of lenses to an optical axis. An AF module is a conventional driving means for moving lenses, and a voice coil motor (VCM) was used as the AF module.

The VCM is a motor developed based on the principle that a diaphragm is vibrated by a force generated between voice current flowing in the coil of a speaker and a magnetic force of a permanent magnet according to the Fleming's left-hand rule. The VCM performs a linear reciprocating motion on a lens at a short distance.

FIG. 1 is a configuration view of a camera lens module according to the present invention. FIG. 1 is a side configuration view illustrating an arrangement state of lenses based on an optical axis Zo.

Referring to FIG. 1, the camera lens module according to the present invention is configured to an optical system in which five sheets of lenses, i.e., a first lens 12, a second lens 14, a third lens 16, a fourth lens 18 and a fifth lens 20 are sequentially arranged from an object. The five sheets of lenses may be formed of various materials. For example, all the five sheets of lenses may be formed of a plastic material.

An infrared filter 22 for filtering infrared wavelengths and an imaging surface 24 are positioned at the back of the fifth lens 20. The imaging surface 24 is a surface on which an image is formed, and an image sensor such as a charge coupled device (CCD) or complementary metal oxide semiconductor (CMOS) sensor is mounted on the imaging surface 24.

In the following description of the configuration of the first lens 12, the second lens 14, the third lens 16, the fourth lens 18 and the fifth lens 20, the term “object side surface” refers to a surface of a lens facing an object based on the optical axis, and the “image side surface” refers to a surface of a lens facing the imaging surface 24 based on the optical axis.

The first lens 12 has a positive (+) refractive power. As shown in FIG. 1, a stop 10 of the optical system is positioned on the object side surface 51 of the first lens 12.

In the present invention, a zooming operation of the optical system is achieved by moving only the first lens 12 to the optical axis. The first lens 12 may be moved along the optical axis by an actuator.

As such, the zooming operation is performed by positioning the stop 10 on the object side surface 51 of the first lens 12 and moving only the first lens 12. Accordingly, although the optical system is configured with the five sheets of lenses, the camera lens module having high resolution can be designed to be slim. Further, when the zooming operation is performed from a wide position to a tele position, a high-speed zooming operation is possible.

The second lens 14 has a negative (−) refractive power. For example, the second lens 14 has a meniscus shape in which the object side surface S3 of the second lens 14 is convex toward an object side.

The third lens 16 has a positive (+) refractive power. For example, the third lens 16 has a meniscus shape in which the object side surface S5 of the third lens 16 is convex toward the object side. The image side surface S6 of the third lens 16 has an inflection point.

The fourth lens 18 has a positive (+) refractive power. The fourth lens 18 has a meniscus shape in which the image side surface S8 of the fourth lens 18 is convex toward an image side. The image side surface S8 of the fourth lens 18 has an inflection point.

The fifth lens 20 has a negative (−) refractive power. Each of the object side surface S9 and image side surface S10 of the fifth lens 20 has one or more inflection points.

At least one of the first lens 12, the second lens 14, the third lens 16, the fourth lens 18 and the fifth lens 20 may have at least one surface formed as an aspheric surface. In the embodiment shown in this figure, all the first, second, third, fourth and fifth lenses 12, 14, 16, 18 and 20 have both surfaces formed as aspheric surfaces. The embodiment in which both the surfaces of all the lenses are formed to be aspheric will be described in detail with reference to the following tables.

FIGS. 2 to 4 show coma aberrations in the first zoom position (tele position), the second zoom position (middle position) and the third zoom position (wide position), respectively.

Each of the graphs in FIGS. 2 to 4 shows tangential and sagittal aberration characteristics according to each wavelength, and it is identified that each line representing an experimental value approximates to the X-axis. It can be seen that the ray aberration correction function is excellent.

FIGS. 5 to 7 are graphs showing lens aberration characteristics according to embodiments of the present invention. FIGS. 5 to 7 show lens aberration characteristics in the first zoom position (tele position), the second zoom position (middle position) and the third zoom position (wide position), respectively.

In each of the graphs, the left graph is a graph obtained by measuring longitudinal spherical aberrations, the middle graph is a graph obtained by measuring astigmatic field curves, and the right graph is a graph obtained by measuring distortion aberrations.

In FIG. 5, the Y-axis indicates the size of an image, and the X-axis indicates a focal distance (mm) and a degree of distortion (%). In FIG. 5, it can be seen that the aberration correction function is excellent as curves approximate the Y-axis. In experimental values shown in FIG. 5, the longitudinal spherical aberration is positioned within a unit of 0.025, and the astigmatic field curves are positioned within the unit of 0.025, which shows a very excellent property.

While the distortion aberration is positioned within a unit of 1.0 in each of the tele position and the middle position, the distortion aberration is positioned within a unit of 3.5 in the wide position, which is relatively high. That is, a slight distortion generated in the wide position is a distortion value generated as a zoom lens is configured to have a micro-miniature size. The distortion can be processed using a separate distortion correcting means provided to an image signal processor (ISP), etc.

FIGS. 8 to 10 are graphs showing modulation transfer function (MTF) characteristics according to embodiments of the present invention. FIGS. 8 to 10 show MTF characteristics in the first zoom position (tele position), the second zoom position (middle position) and the third zoom position (wide position), respectively.

Here, MTF refers to a ratio value obtained by calculating a difference between the original image of a subject and the image formed by passing through a reflection or refraction surface. The MTF is a value related to resolution of the camera lens module.

In FIG. 8, the linear dotted and solid lines positioned at a top end indicate reference lines for the sagittal fields (X- and Y-axes) and a reference line for the tangential field (Z-axis). It can be seen that the curves (designated by dotted and solid lines) of each of the fields, positioned at a bottom end, have excellent resolution as they approach the reference lines.

Referring to experimental values of FIG. 8, it can be seen that the curves of each of the fields approach the reference lines in the tele position and the middle position, and the embodiments of the present invention have very high resolution. Since curves of most fields except some fields approach the reference lines at the top end, it can be seen that the embodiments of the present invention also have very high resolution.

FIGS. 11 to 13 are graphs showing through-focus characteristics according to embodiments of the present invention. FIGS. 11 to 13 show through-focus characteristics in the first zoom position (tele position), the second zoom position (middle position) and the third zoom position (wide position), respectively.

FIGS. 11 to 13 show through-focus values that become references when assuming a parabolic solid line having maximum and minimum points has a resolution of 100 line pairs. It can be seen that the graph measured for each of the fields has an excellent through-focus value as it approaches the parabolic solid line

Referring to FIGS. 11 to 13, it can be seen that the graph measured for each of the fields has a parabolic form and thus approaches a reference graph.

Although the present invention has been explained by the embodiments shown in the drawings described above, it should be understood to the ordinary skilled person in the art that the present invention is not limited to the embodiments but rather that various changes or modifications thereof are possible without departing from the spirit of the present invention. Accordingly, the scope of the present invention shall be determined only by the appended claims and their equivalents.
